Product Summary

A butterfly throttling valve is the mechanism by which the flow of a fluid is managed by constriction or obstruction. An engine's power can be increased or decreased by the restriction of inlet gases (i.e., by the use of a throttle), but usually decreased. The term throttle has come to refer, informally and incorrectly, to any mechanism by which the power or speed of an engine is regulated. What is often termed a throttle (in an aviation context) is more correctly called a thrust lever. For a steam engine, the steam valve that sets the engine speed/power is often known as a regulator.

Throttling Butterfly Valves are available in a wide range of sizes, materials and flange types. A direct drive design provides a fast response in order to quickly achieve the desired pressure. The valves are equipped with high quality stepper motors and specially made i901 controller. The result is excellent process capability in a very cost effective package.

The Throttling Butterfly Valves have the features and benefits as follow: such as small footprint, wide variety of sizes available, standard flange-flange dimensions to facilitate easy competitive, change-out, direct drive motor to eliminate extra moving parts and sources of wear and particles and so on.

Provided is a Throttling Butterfly Valves of an internal combustion engine capable of absorbing a dispersion in valve opening degree at closed positions to reduce a leakage of air by solving problems, for example, with a multi-arrayed variable intake valve device in which a plurality of throttle valves mounted on a single turning shaft are opened and closed, a dispersion in valve opening degree is liable to occur at the closed positions due to the mounting errors of the throttle valves on the turning shaft and, accordingly, it is difficult to reduce the leakage of air.
